Comment 7 for bug 1361137

So, on krillin rtm image 6, I can enable passphrase lock mode and it seems to work. If I switch back to swipe, it asks me for the passphrase then sets the lock back to swipe. Also seems to work fine.

Same thing if I switch it to PIN and then back to swipe. The screen briefly selects 'passphrase' but after a split second the UI selects 'swipe' and the change takes effect.

However, after installing rtm silo 003 (contains a bugfix for this and bug 1350381), it no longer works. What happens is:
- Select 'passphrase'.
- Enter a passphrase twice, and click 'set'.
- The screen freezes for a few seconds, then a dialog pops up saying "Could not set security mode", wanting me to enter the passphrase again.
If I then hit 'cancel', it goes away and I can see the changes actually took effect. Unlocking requires a passphrase.

Then if I select 'swipe' right after unlocking the screen, when the auth token should still be fresh, it asks me to enter the passphrase to switch to swipe... which means the other bug wasn't totally fixed either. But I can at least just hit 'cancel' and have the phone switch back to 'swipe' mode.

So, it asks for a passphrase in at least two situations where it shouldn't.
